Text Formatting ⇒ I cannot input accented letter from external file.

[fpires]

Hello, everyone!

Well, I have a simple question. If I write the code below, everything works good.

Code: Select all

\documentclass[a4paper,12pt]{report}
\usepackage[utf8]{inputenc}
\begin{document}
Hello, world.
\newwrite\temp
\immediate\openout\temp=Test
\immediate\write\temp{This is a test.}
\immediate\closeout\temp
\input{Test}
\end{document}

However, I need to write letters with accent in my text, and because of that I use

Code: Select all

\usepackage[utf8]{inputenc}

in the preamble. If the accented letter is in the text itself, it is printed normally, but if it is written in the external file, I cannot run the code. For example, if I write

Code: Select all

\documentclass[a4paper,12pt]{report}
\usepackage[utf8]{inputenc}
\begin{document}
Hello, world.
\newwrite\temp
\immediate\openout\temp=Test
\immediate\write\temp{This is a test. á}
\immediate\closeout\temp
\input{Test}
\end{document}

I get the following error message:

! Undefined control sequence.
l.1 This is a test. \unhbox \voidb
@x \bgroup \let \unhbox \voidb@x \setbox \...

The external Test file looks like this:

Code: Select all

This is a test. \unhbox \voidb@x \bgroup \let \unhbox \voidb@x \setbox \@tempboxa \hbox {a\global \mathchardef \accent@spacefactor \spacefactor }\accent 19 a\egroup \spacefactor \accent@spacefactor 

Would any of you have a solution for this problem? I suppose it is simple, but I am not exactly very used to Latex.

Thank you in advance!

Hi Felipe!

A simple way is, to not expand the letter to code:

Code: Select all

\immediate\write\temp{\unexpanded{This is a test. á}}

Or protect it, so it won't get expanded as well:

Code: Select all

\makeatletter
\immediate\protected@write\temp{This is a test. á}
\makeatother
